Richter Bellows Sealed Control & Shut-Off Valves
Richter Bellows-Sealed Control & Shut-Off Valves are PFA / PTFE lined globe valves with PTFE bellows replacing the conventional gland packing, providing hermetic atmospheric isolation for toxic, corrosive and hazardous fluids. Sizes DN 8 to DN 100, pressure rating PN 10 to PN 25.
Welded PTFE bellows isolates the stem from the pumped fluid, eliminating any leakage path through the stem-bonnet interface. PFA / PTFE lining throughout the body for complete chemical compatibility. Plug or parabolic disc options for shut-off or throttling control. Hand wheel, pneumatic or electric actuator operation. Compliant with TA-Luft and EN ISO 15848 fugitive-emission standards.
